There are 16 cars and 64 passengers scheduled to go to a concert. write a ratio in simplest form like compares the number of passengers to the number of cars.

64:16 (Simplified is 4:1) For every 4 passengers, there is 1 car.

Whatever group is first, you put the amount of items in that group first in the ratio. (Since it's comparing passengers to cars, you put the amount of passengers first.) Then, simply divide both sides by their GCF (Greatest Common Factor) which is 16. So, the ratio you're left with is 4:1 (4 passengers for every 1 car)

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
